I have 3 roommates, 2 of them being a married couple. I was asked last night if I could do something like the image posted below for them for Christmas. It doesn't look like too difficult of a shot, I just am unsure about it. I feel like it might be a little tough to get just right.

I have to work with, a 5D3, 50mm 1.4, 100mm 2.8, and the 24-105L. Any tips or suggestions would be fantastic.
